1. Description
REX640 is a powerful all-in-one protection and control relay for
use in advanced power distribution and generation applications
with unmatched flexibility available during the complete life
cycle of the device – from ordering of the device, through
testing and commissioning to upgrading the functionality of the
modular software and hardware as application requirements
change.
The modular design of both hardware and software elements
facilitates the coverage of any comprehensive protection
application requirement that may arise during the complete life
cycle of the relay and substation.
REX640 makes modification and upgrading easy and pushes
the limits of what can be achieved with a single device.
2. Application packages
REX640 offers comprehensive base functionality. However, it is
possible to further adapt the product to meet special installation
needs by including any number of the available optional
application packages into a single REX640 relay. For the
selected application packages, the functionality can be
extended by including the related add-on package. The
REX640 connectivity package guides the engineer in optimizing
the application configuration and its performance.
